The diverse services needed by young children with disabilities, chronic illness and developmental delays can challenge both their families and the support systems they rely on. This book provides a pragmatic approach to helping these children that empowers families, builds on competencies and resilience, and has a strong empirical basis. The cornerstone of this programme is its focus on the larger systems that support the child. This book describes how to meet the needs of children and their families while enhancing collaboration among service providers. Psychologists and programme administrators, and other service providers reading this volume should learn a systems-based approach to early intervention with infants and young children that draws on a specific understanding of community, agency and family context. This programme is based on a solid knowledge of normal and delayed development, illness and disability and builds on professionals' natural desire to deliver services that enhance the functioning not only of the child, but of his or her family. This model of childhood intervention creates allies among agencies in a win-win approach to helping our youngest citizens.
